From Post #48 as well
Not sure I understand your PV wire sketch. Text at top says 48V 24.7A
Is that the rating for each panel, or each string?
For a MPPT controller to work well with a 48V battery bank, you need to supply at least 1.5x battery voltage, up to 2x battery. So 73V of array would be the least, up to 96 for the best efficiency in the Controller. Going higher voltage may be desired if you have long runs ........
I stand corrected.
